Bug fix and maintenance release

• updates in class GDALAlg, experimental bindings to the new GDAL CLI API (Multiple updates for the gdal CLI bindings #782)
  • improve input validation
  • ensure algorithm names originating in Rcpp::CharacterVector are always passed explicitly as const char * in C API calls
  • fix clang compiler warning from -Wunused-const-variable
• add gdal_global_reg_names(): return a character vector containing the names of the algorithms in the GDAL global algorithm registry (Multiple updates for the gdal CLI bindings #782)
• handle GDAL CPL error messages via Rcpp, and suppress driver warnings during package initialization (Handle GDAL CPL error messages via Rcpp and suppress driver warnings during GDALAllRegister() #784)
• plot_raster(): use on.exit() for par() reset (plot_raster(): use on.exit for par reset #780)
• fixes in several unit tests, mainly fixing on.exit() cleanup code (Fixes in several tests mainly fixing on.exit() cleanup code #783)
• Documentation
  • update text in the "Development Status" section describing the experimental GDAL CLI bindings
  • condition the example code for the CLI bindings on the availability of top-level algorithm names from the global algorithm registry (for now, until the upstream API is declared stable)
  • remove some non-ASCII characters found in .Rd files and other miscellaneous improvements in .Rd formatting
